Azalea Wilting

Question

I have three azaleas in a raised brick planter. They were planted about 3 years ago. We dug a good size hole and filled it with special azalea potting soil that we got in bulk from our local nursery. The plants have barely grown since then and tend to lay like vines on the soil surface. I fertilize them once or twice a year with a mild acid fertilizer. They only get one or two blooms on each plant and now they are starting to wilt, branch by branch. I checked to make sure that they were getting enough water, and the soil seems moist but not too wet. They get filtered light. We had a mild winter, so no chance of frost damage. We have had a consistent 62 low at night-mid to low 80 inchess in the day. The leaves are a light green in color. Can you help me?

Answer 1

This is either a watering issue (too much or too little) or azalea root rot.
